How to Find Harmonics in an AC Signal
应用文章
Introduction
Harmonic distortion has become increasingly prevalent in today’s world due to the expanded use of equipment and machinery. Because these devices can malfunction or fail in the presence of high harmonic voltage and/or current levels, harmonic distortion has become a growing concern for facility managers, users of automation equipment, and engineers. The presence of harmonics may not impede a factory’s or office’s ability to run properly, however, it depends on the withstand capability of the power distribution system and the susceptibility of the equipment. In this application note, you will learn some basics about harmonics and how to perform a quick check for harmonics in electrical power systems.
